The American Counseling Association has cancelled its plan to hold a conference in Nashville next year in protest of Tennessee passing a counseling law that allows therapists to decline to see patients based on religious values and personal principles.

The ACA made the announcement on Tuesday that it had cancelled the already booked expo in the Music City.

The ACA, which has condemned Tennessee’s new law as a “hate bill” that discriminates against gay, lesbian, bisexual and transgender people, has called the legislation an unprecedented attack on its profession. The organization says no other state has passed such a law.

Supporters of the law have said that it keeps the government from forcing people to counsel others to act in ways that conflict with a therapist’s moral beliefs.
